Trait BitmapSlice

pub trait BitmapSlice: Sized {
    // Required methods
    fn alloc(self, n: usize) -> Option<usize>;
    fn free(self, index: usize, n: usize);
}

Like Bitmap, but for arrays. This is unfortunately needed due to conflicting implementations.

Required Methods

fn alloc(self, n: usize) -> Option<usize>

Find n consecutive unset bits, set them and return the index of the first bit. This is useful for memory managers using Bitmap to track free frames / pages.

fn free(self, index: usize, n: usize)

Free n previously allocated bits, starting at index.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
